High-pressure test plugs for pipes and flanges for chemical plants
CURTISS-WRIGHT Corporation HIGH LIFT FLANGE/WELD TEST PLUG
Localized pressure testing of flange construction to improve safety.
In the chemical plant industry, ensuring the safety of piping is the most critical issue. Particularly in piping that handles high-pressure fluids, the reliability of welds affects the overall safety of the plant. Leaks due to welding defects pose a risk of serious accidents, making reliable pressure testing essential. Our high-pressure pipe and flange pressure test plug is designed to allow localized pressure testing after welding in flange construction. This enhances the safety of the plant. 【Usage Scenarios】 - Pressure testing after welding in chemical plant piping construction - Pressure testing of piping during plant maintenance - Purging and upstream monitoring during welding 【Benefits of Implementation】 - Localized testing eliminates the need for ancillary work, reducing labor and costs - Reusable, helping to control running costs - Reduced environmental impact through minimized media usage
